Abstract

The invention relates to a machining tool, in particular to a rapid type drill bit special for drilling and bottom expanding and capable of improving efficiency. A main body of the drill bit is composed of a drill bit body and bottom expanding wings. The drill bit is characterized in that the drill bit body is a cylinder, a cutting edge is arranged on the drill bit body, and cutting speed can be increased; two pairs of bottom expanding wings are arranged on the two sides of the drill bit body and provided with sawtoothed small drill bits, the overall broaching speed of the drill bit can be increased, and work efficiency is improved.

Description

End target drill is expanded in a kind of Quick-type probing of raising the efficiency
Technical field
The present invention relates to a kind of machining tool of drilling project, end target drill is expanded in a kind of Quick-type probing of raising the efficiency.
Background technology
drill bit goes out through hole or blind hole in order to drilling on processing work, and can to the cutter of existing hole reaming.Drill bit is used in a lot of field, comprises machinery, drilling well, medical, timber, stone, glass etc., and expands the machining tool that subdrilling is a kind of drilling project, and its structure is simple, and simple to operate, safety factor is also higher.Invention increases cutting blade and the reaming wing, add the speed of probing.
Summary of the invention
The object of the invention is to invent a kind of Quick-type probing of raising the efficiency and expand end target drill.
End target drill is expanded in a kind of Quick-type probing of raising the efficiency, main body is made up of drill body and the expansion end wing, its innovative point is: described drill body is cylinder, and described drill body is provided with cutting blade, and described drill body both sides are provided with two to the expansion end wing.
Further, the length of described drill body is 1.5m ~ 2.0m, and diameter is 0.5m ~ 0.8m; Structure is hollow cylinder.
Further, described drill body is provided with helical form cutting blade, connects around drill body front end.
Further, described drill body both sides are respectively provided with two to the expansion end wing, expanding the end wing is equilateral triangle structure, and the length of side is 0.5m.
Further, the triangle hypotenuse that the end wing is expanded in described location is provided with zigzag miniature bur, and be evenly distributed in and expand on the end wing, two to symmetrical, and the reaming of the same side is interplane every 0.2 ~ 0.5m.
Further, described drill body is provided with circular heat elimination hole, and diameter is 0.2 ~ 0.5m.
Beneficial effect of the present invention is:
1, probing body of the present invention, through quenching technical process, sturdy and durable, there is certain toughness, not fragile, surface is sprayed with water proofing property paint, can effectively prevent drill body from getting rusty, affect application life.
2, drill body of the present invention is provided with helical form cutting blade, cutting blade material is carbide alloy, sturdy and durable, not easy to wear, can drilling rate be improved.
3, drill body both sides of the present invention are respectively provided with two pairs of reaming wings, reaming speed can be increased.
4, the reaming wing of the present invention is dispersed with zigzag small-sized boring, can the needs of better match-drill, improve drilling efficiency.
5, drill body of the present invention is provided with circular heat elimination hole, effectively can increase heat dissipation capacity, increase the service life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 is structural scheme of mechanism of the present invention.
Fig. 2 is the cutting end view of drill bit of the present invention.
Detailed description of the invention
Bottom expanding drill as shown in Figure 1, by drill body 1, cutting blade 2, the reaming wing 3, jagged bit 4 and circular heat elimination hole 5 are formed.
The structure of straight shank drill is as shown in Figure 1: drill body 1 is cylinder, and the length of drill body is 51.5m ~ 2.0m, and diameter is 0.5m ~ 0.8m, and structure is hollow cylinder, and it is simple and easy loaded down with trivial details that the design of this structure is mainly considered when drilling.
One end of straight shank drill is drill body 1 as shown in Figure 1, and drill body 1 is provided with cutting blade 2, can accelerate reaming speed, increase work efficiency.
Described drill body 1 both sides are respectively provided with two pairs of reaming wings 3, reaming speed can be increased.
The described reaming wing 3 is provided with zigzag miniature bur 4, can the needs of better match-drill, improves drilling efficiency.
Described drill body 1 is provided with circular heat elimination hole, effectively can increase heat dissipation capacity, increase the service life.
During probing, cutting blade 2 first touches the bottom of having bored hole, carry out secondary cutting, the position reprocessing do not processed, when rig turns round, under drilling tool Gravitative Loads, the wing 3 at the bottom of expansion is made to open gradually, carry out at the bottom of expansion for cutting hole wall, jagged bit 4 also comes into operation, and accelerates cutting speed, just completes through reaming after a period of time.
The above is the preferred embodiment of the present invention, can not limit the interest field of the present invention with this.It should be pointed out that for those skilled in the art, technical scheme of the present invention is modified or equivalent replacement, do not depart from protection scope of the present invention.
